Further complications arise when the lower walls of the mother zooid become thickened and interpenetrated with solenia, from which buds are developed, so that lobose, tufted, or branched colonies are formed.The chief orders of the Synalcyonacea are founded upon the different architectural features of colonies produced by different modes of budding.
